The present invention relates to a `method l narrow band asa rule, mustbe visible on the 1 imposed upon the tax band-one must be ydisplacedfrom the other so thatone edge ofthe' tax bandwill be visible. Y l

Formerly banding with two diierent bands was accomplished by having theband applying device operate with two magazines of' bands,

the device drawing a band from one magazine.

and applying it and then being shiftedto draw a band from the second`magazine andapplying it over the rst. Such a device is not only com-fplicated in construction and delicate because of the various motions itmust have, but itis slow. A single cigar. must remain in the region ofthe banding devicev while the deviceperf. forms two' operations. vi

A considerably more rapid and satisfactory method of banding rwith twodiiierent'bands is to employ two banding devices of similary .con-`struction and move the cigars successivelypast 30 them. One of the-devices applies the first' bandf and the second applies the secondband.

The presentinvention has for its object to provide means whereby twosimilarly constructed banding devices may be used'to apply 35 two bandsin partly overlapping relation. f

Another object is to provide means in which two bands of differentwidths may be applied in the desired relation on a cigar.`

A further object is to provide a continuous banding device to accomplishthe ab'ove'named objects. v

Another object is to provide a method of peration for use in applyingtwo or more super imposed bands on a cigar in partly overlappedrelation. Y y

In general the Ainvention is carried out by moving the cigar past twosimilar banding devices and eiecting, after the iirst band has 'beenapplied, an axial displacement between the cigar and the second bandingdevice. In one forni .of construction this effect is produced by havingthe second banding device of a shorter amplitude of movement than therstwhereby the second band is placed nearer to the end of the cigar thanthe rst byv anamount sufficient so that The presence of a1 A portion ofthe tax band,v which is acigar so that if the ornamental band be superaportion of vthe underlying band will remain visible afterthe upper bandis applied.

Another construction to accomplish the purpose consists in' locating oneof the banding devices closer to the path of themoving cigars than theother whereby the same amplitude of movement places the bands indifferent positions on' thev cigar. Althird type of constructioninvolves the displacement of the cigar itself after it leaves-the firstbanding device.

With 4the foregoing and other objects in View, theinvention will be morefully described hereinafter, .and will be more particularly pointed out,in the claims `appended hereto.

Referring now to Figures 1 and 2,12 represents avvork4 table which isprovided along its length with a pair Yof slots 2 in which operates aninter-f mii-tentY conveyor l which has troughs or cradles 3 atspacedpoints to receive cigars Z. Thisconveyor is driven in any of a'number ofwell known manners to produce a vstep by step advance of the cigarsalong Ithe table in the direction. of the arrow in Figure 1. The cigarsZ are held in linev by means of a guide 8 which runs parallel to theconveyor I. At spaced points along the conveyor |-the band applyingdevices 4 andl 5 are located. These devices are shown in dotted lines inFigures land 2 and areof well understood construction. For instance theband applying devices may be of the type shown in the patent to MalocsayNo; 1,261,831. It will be noted from Figure 1, that the band applyingdevice 5 isr nearerto the left run'of the' conveyor I than is thebandapplying device 4. Opposite the device 4' is ka feeding head 4' which,as is well known, is constructed of hollow arms connected at one endwith a vacuum pump and open at the other end, as foi-instance, is shownin the Malocsay Patent No..v 1,261,831. The ends of the head 4', nearestto the conveyor rl, are upturned and open. The

head 4' is carried by `a bracket 20 which is secured pivotally to thetop of an arm 2|. The bracket 20 is likewise pivotally secured to thetop of an arm 22 which as shown is of adjustable length. The arm 2| ispivotally secured to a shaft 23 running lengthwise beneath the table 2.This arm 2| moves the bracket 20 and head 4 into and out of the path ofthe cigars. The required motion is produced by the rotation of a shaft24 carrying a cam disc 25 against which bears a roller 26 on the arm 2|.The roller 26 is yieldably pressed against the edge of the disc 25 bymeans of a. spring 21 secured at one end to the arm 2| and at its outerend to the bracket 28 fastened to the table 2. As the shaft 24 isrotated the arm 2| swings about the shaft 23 and advances the head 4' toa position beneath the banding device 4. The head 4 is rocked in avertical sense by means of the adjustablearm 22 which is pivotallysecured at its lower end to a yoke 29 pivoted on the shaft 23 andcarrying at its opposite side a short arm 30 which'carries a' roller 3|.A smaller cam disc 32 fixed to the shaft 24 provides the motion for thearm 30 and the adjustable arm 22. The roller 3| is retained against theedge of the disc 32 by means of the spring 33 fastened at one end to theshort arm 30 and at its opposite end to the table 2. It will be seenthat in the position shown in Figure 2 the roller 3| is riding on thehighest point of the disc 32 and the head 4 is in its uppermost positionagainst the bottom of the stack of bands Zu' which-areheld inthe'magazine 6. This .magazine, as is well known, is open at thebottomand the open upper ends of the head 4 are applied against; thesurface of the lowermost band Zu. For example of the details of thisstructure see Malocsay Patent No. 1,261,8311.4 'Ihe suction in the head4 is suflicient to pull this lower band 40 away from the stack whenthe'head 4.' is` moved downwardly as the roller 3| rides downA on alower portion of the cam disc 32. The band Zu' is thenY carried with thehead 4' out beneath the applying device 4 which wraps it and secures it45 about the cigar Z. V

The band applying device 5 has located` opposite it a feeding head 5' ofidentical structure with Ythe head 4. The head 5 moves in the directionof the cigars a shorter distance than 50 the head 4'. The amplitude ofmovement of the head 4 isA indicated by the length line marked X` inFigure 1 while the 'amplitude of the head 5 is indicated by the lengthline Y. The shortening of the stroke of the head 5 is accomplished by 55reducing the maximum diameter of the cam disc corresponding to the disc25 associated'with the head 4. Such a reduction in diameter is indicatedin dotted lines in Figure 2.

The movement of the conveyor I and the oper- 60 ation" ofthe heads 4 and5' and of the band applying devices 4 and 5 is timed so that a cigar isVplaced in front of Teach of the devices and stopped long enough forthedevices to perform theiroperations and then the conveyor moves 65suffcientlyto place a subsequent cigar opposite each of the devices.'Such synchronous operation of the conveyor, the band feeding, and theband applyingunits'is well-known in the art and may be accomplished byadopting a driving mechanism 70 such as shown in the U. S. patent toSchmiedel No: 2,065,029.` The structure above-referred to forms no partof this invention or the claims directed thereto. In this way, theoperation of the banding machine 'is constant and the second 75 band isbeing applied to one cigar as the'rst is second band applying devices.

being applied to another; thus, only the time of a single bandingoperation is consumed. In the drawings the first band, usually the taxband, is indicated by Zu and held in the magazine 6. 'I'he second bandZu" is the ornamental or identifying band and is held in the magazine 1.The ornamental band Zu is placed nearer to the round end of the cigarthan the tax band by an amount sufficient to leave a substantial portionof the tax band visible. The magazines I5` and 1 and the feeding heads4' and 5 are placed on the table 2 in line with one another, that is,they are spaced equal distances from the conveyor I.

` The only difference in the devices is that the band applying device 5is nearer the left hand run of the conveyor than is the band applyingdevice 4 and the stroke of the feeding head 5 is shorter as explained.

Figures 3 and 4 illustrate the second form of construction. In thisconstruction identical band feeding heads 4 and 5'vare used. The strokeof each also is the same, the cam disc of the feeding devices beingidentical. The variation in the position at which the band is applied isobtained by locating the entire feeding head assembly 4 nearer to theleft run of the conveyor I than the feeding head assembly 5'. The bandapplying devices 4 and 5 are located as in the previously described formof construction shown in Figures 1 and 2. Figure 4 shows clearly thelateral displacement of the magazines 6 and 1, the magazine 1 beingfurther away from the ends of the cigars than the magazine 6. The resultof this construction is that the same magnitude of stroke in the twofeeding heads 4' and 5 produces different positloningsfof the bands Zu.and Zu upon the cigar. s

Referring now particularly to the thir'd form of construction as shownin Figures 5 and 6, the band applying devices 4 and `5 are showndirectly inline with regard to the conveyor I. The feedirgheads 4' and5' togetherwith their respective magazines 6 `and 'l are likewiselocated in the same longitudinal line on the table 2. In thisconstruction the cigar itself ismoved before the second band is applied.The cigars are held in line at Vthe end of the table 2 adjacent the bandapplying device 4 by means of a short guide rail I1 which ends somewherebetween the rst and After the end of the guide` rail I 1 another shortguide |8 is located on theV table at a point further removed from theconveyor Opposite a portion of the guide` I8 a pusher 9 is located andsynchronized with the conveyor and the band applying device so that whenthe cigars stop it pushes one of them against the guide I8 thus shiftingit lengthwise before it arrives opposite the second banding device 5. Asshown in Figure 6 the pusher 9 is composed of a rod 9' slidably mountedin a pair of spaced blocks I0. 'I'he end of the rod S opposite thecigars extends over the edge of the table 2 .and carries a pin 34 at oneside. A bell crank lever II is pivotally mounted on the table 2 by meansof the pivot I2. At its upper end the lever II' carriesI a yoke 35 whichfits around the pin 34 and transmits the motion of the lever thereto. Atits lower end the lever II'carries a roller I3 which plays against theedge of a cam ldisc 36 and against which edge it is held by means of thetraction spring I4 attached at one end to the lower arm of lever I I andat the' other end to a portion of the table 2. rI'he disc 36 is mountedon they shaft 24 with the discs controlling the feeding heads 4 and 5and rotates with them.

At the same time that the feeding heads advance a band over a cigar thepusher 9 advances against the end of a cigar Vadjacent to it and shiftsit by an amount'sufcient to place it against the guide I8. The amount ofthis movement issufflcient to produce the desired displacement of thesecond band Zu awayfrom the first band Zu'.

The invention above described is not limited, ofcourse, to theparticular bands applied but the need for spacing the tax band and theornamental band of a cigar forms one useful purpose to which theinvention may be applied. In its broader sense the invention consists inemploying banding devices of the same type at spaced points. The cigaris moved past the banding devices and some time before the rst and thesecond of said devices a shift lengthwise of the cigar is producedbetween the position of the rst band and that of the second.
